javascript - Why would I be getting a "missing ) after argument list" error? - Stack Overflow

I am working on an AJAX system to submit a form, but I can't even get my JavaScript to load, the Firebug report is below.

missing ) after argument list
    else if( httpRequest.responseText == 'already logged in' )\n

I poked around the internet and SO, but all I found was errors in quoting. (Example, Another Example). I don't have anything misquoted, so I really don't see what is going on. More of my code is below.
(Some unrelated function calls to remove loading messages are removed.)

if(httpRequest.responseText != "failure")  // Works fine!
{
    document.getElementById("result").innerHTML = "[Success message]";
    setTimeout("2000", function(){ window.location.assign("[link to page]");
}
else if(httpRequest.responseText == 'already logged in')  // Similar to above, but fails
{
    document.getElementById("result").innerHTML = "[error message]";
}
else
{
    document.getElementById("result").innerHTML = "[error message]";
}

Might anyone know why this error is called?

Sorted by: Reset to default 7

the line

setTimeout("2000", function(){ window.location.assign("[link to page]");

misses a }) causing the next line to fail (the whole syntax is wrong anyway:)

it should be

 setTimeout (function(){ window.location.assign("[link to page]") } , 2000 );

setTimeout takes a function as the first parameter and an integer as the second one.

If you split your code up a bit more you see the problem:

setTimeout("2000", function()
{
    window.location.assign("[link to page]");

So you are missing a } and a );

setTimeout(function()
{
    window.location.assign("[link to page]");
},2000);

Edit: The order of the arguments is wrong as well like Caspar pointed out.

   setTimeout("2000", function(){ window.location.assign("[link to page]");

should be

   setTimeout("2000", function(){ window.location.assign("[link to page]");});

You are missing the }); here

setTimeout("2000", function(){ window.location.assign("[link to page]");

should be

setTimeout("2000", function(){ window.location.assign("[link to page]"); });
